I flew the shuttle SEA-SFO on 3/1. UA brought in a 747-400 from SFO that was going to SYD later that night. Using this plane for the shuttle was a surreal experience--Upstairs, empower, noise-canceling headphones, arrival at the international terminal. Service was more shuttle like--a plastic cup of juice, bag of snacks, but lots of those small liquor bottles for those so inclined.
